Tracker Proxy does not work under Matomo 4.6.2

Support & Bugs
1

Hi,

I was happily using the tracker proxy to hide my matomo Url and it worked fine under Matomo 3.x:

However, now I upgraded to Matomo 4.6.2 and it is not working anymore. The calls to proxy file in the tracking code now return a 400 Code.

Does anybody know where the problem could be?

Thanks

Jens

I solved the problem:

When updating to matomo 4.6.2 the database update did not work correctly. I saw the following error message in the matomo debug messages:

Unknown column ‘config_client_type’ in ‘field list’

So I updated the database with this mysql command:

ALTER TABLE matomo_log_visit ADD COLUMN config_client_type TINYINT( 1 ) NULL DEFAULT NULL;

Now the tracker proxy works again like a charm.

By the way: if you rename the tracker proxy directory and file to something other than “piwik” or “matomo”, the browser tracking filters won’t block you … :slight_smile:

So the tracker proxy still works with matomo 4.6.2

Cheers

Just to be complete in case someone else encounters this problem:

I also had problems with ecommerce tracking after updating. The cart content was not transmitted via api.

After setting the incredibly helpful “debug_on_demand = 1”, I discovered that the column config_client_type was also missing from the log_conversion table.

I solved the problem with this mysql command:

ALTER TABLE log_conversion ADD COLUMN config_client_type TINYINT( 1 ) NULL DEFAULT NULL;

Cheers
Jens
